IP68 with AUMA 3-phase AC motor
Standard:
Enclosure protection according to
EN 60529
According to AUMA definition, enclosure protection IP68 meets the following requirements:
●
Depth of water: maximum 8 m head of water
●
Duration of continuous immersion in water: Max. 96 hours
●
Up to 10 operations during continuous immersion
For exact version, refer to actuator name plate.
Pollution degree 4 (when closed) according to EN 50178
Pollution degree
2 g, from 10 to 200 Hz
Resistant to vibration during start-up or for failures of the plant. However, a fatigue strength may not be
derived from this. Valid for multi-turn actuators in version AUMA NORM (with AUMA plug/socket con-
nector, without actuator controls). Not valid in combination with gearboxes.
Vibration resistance according to
IEC 60068-2-6
KS: Suitable for use in areas with high salinity, almost permanent condensation, and high
pollution.
Standard:
Corrosion protection
KX: Suitable for use in areas with extremely high salinity, permanent condensation, and
high pollution.
Option:
